unsigned char * shown incorrectly in locals and expressions

Instead of displaying the contents of the current address, the current address is displayed on 100 items.In QtCreator 4.1,it show correctly;
example:unsigned char* data=(unsigned char*)"\x11\x22\x33\x44";
data's address=0x40092c
in 4.2.0 show 10 items
[0] 0x2c [1]0x09 [2]0x40 [3]0x00 [4]0x00 [5]0x00(incorrect)
